Midterm elections likely to boost US stocks despite political turmoil

The upcoming US midterm elections, set for nine days from now, are expected to shift control of the House to Democrats and possibly the Senate as well, a development that will embarrass President Donald Trump. Regardless of the political fallout, historical patterns show that the S&P 500 has risen in each of the 12 months following a midterm since 1950, with an average increase of 15%. The most dramatic rise was 43% after the 1954 elections, and the smallest was a modest 3% after 1986, even though that year featured the Black Monday crash.

Market analysts argue that a split Congress—different parties leading the two chambers—usually limits major legislative action, allowing businesses to focus on profit generation. Under Republican presidents, such divided control has produced the highest equity returns, suggesting that a Democratic House paired with a Republican Senate could be especially market-friendly. US corporations are already reporting strong earnings, with S&P 500 members up 29% year-over-year, reinforcing optimism for continued stock gains.
